Abstract:
A method of forming a metal container (40) comprises: narrowing a first top section (42) of the container (40) in at least one narrowing step, wherein after narrowing the first top section (42), the first top section (42) has a first top section minimum outer diameter (44); and narrowing a second section (46) of the metal container (40) after narrowing the first top section (42), wherein after narrowing the second section (46), the second section (46) has a second section minimum outer diameter (48); wherein the second section (46) is below the first top section minimum outer diameter (48) and wherein the second section minimum outer diameter (48) is larger than the first top section minimum outer diameter (44). In some embodiments, the second section (46) is below the first top section minimum outer diameter (44). In some embodiments, the second section (46) of the metal container (40) is necked with a necking die (32). In some embodiments, a minimum inner diameter (88) of the working surface of the necking die (92) is greater than the first top section minimum outer diameter (84). In some embodiments, the step of narrowing a second section (86) of the metal container (80) to a second section minimum outer diameter (88) comprises passing the necking die (92) beyond the first top section minimum outer diameter (84).
Abstract:
The present invention relates to a method for manufacturing an inner structure of a regenerative cooling type combustion chamber, and more specifically to a method for manufacturing the inner structure of the regenerative cooling type combustion chamber, including the steps of: manufacturing a cylinder structure by performing a vacuum casting process or an air casting process for a copper alloy; manufacturing a circular plate having a constant thickness by forging and rolling the cylinder structure; thermally and mechanically processing the circular plate; spinning the circular plate to manufacture the shape of the regenerative cooling type combustion chamber; and thermally processing the shape of the regenerative cooling type combustion chamber. The method for manufacturing the inner structure of the regenerative cooling type combustion chamber can prevent necking and damage of the structure and can improve reliability during a bulging process for assembling the inner structure with an outer structure of the combustion chamber by uniformizing and miniaturizing the grain size of the inner structure of the combustion chamber.
Abstract:
An article of manufacture includes a first rotor having a first flow-through, area that is more than 50% of a total first rotor flow area and a first ridged arc member, and a second rotor having a second flow-through area that is more than 50% of a total second rotor flow area and a second ridged arc member. The article further includes an upstream, stator and a downstream stator, each stator having a co-extensive stator flow-through area and a co-extensive structural area. The article includes an actuator having an engagement gear between the ridged arc members, where a turn of the engagement gear moves the ridged arc members in opposing directions. The first rotor and second rotor are phased to he ai a maximum closed at a first position of the engagement gear and a maximum open at a second position of the engagement gear.
Abstract:
According to the preferred embodiment, an improved method and apparatus for the manufacturing of an aluminum tube and aluminum fin heat exchanger that includes steps for pneumatic cleaning, thermal cleaning, and uncontrolled-atmosphere open-flame autobrazing of hairpins to return bend fittings. The method uses a tube lubrication system that is adjustable to control amount of lubrication applied to the tube prior to final expansion. The method uses a pneumatic coil cleaning station that is adjusted to reduce the residual oil particulate from the expansion process required to be thermally cleaned.
Abstract:
A can rounding system and method that uses arms that are able to maintain cans in a concentric arrangement during the welding process. The arms enable the can rounding system to maintain the concentric positions in order to achieve improved circular dimensions and increase the overall efficiency in the construction of cylindrical and conical structures, such as wind towers.
Abstract:
The invention is hollow structural members, a rail system based thereon and method of manufacturing such hollow structural members. Embodiments of the structural members may be hollow triangular prism-shaped with a cross-section that is triangular, isosceles, hexagonal or otherwise. Embodiments of rail systems based on hollow structural members are also disclosed. Embodiments of the rail systems disclosed herein may also include reaction assemblies for local dissipation of stresses due to thermal expansion of track materials.
